Abstract: Pastewka and Robbins (2014, “Contact Between Rough Surfaces and a Criterion for Macroscopic Adhesion,” Proc. Natl. Acad. Sci., 111(9), pp. 3298–3303) recently have proposed a criterion to distinguish when two surfaces will ...

Abstract: Recently, it has been shown that while asperity models show correctly qualitative features of rough contact problems (linearity in area–load, negative exponential dependence of load on separation which means also linearity ...

Abstract: We show that the full multiscale Persson's theory for rubber friction due to viscoelastic losses can be approximated extremely closely to simpler models, like that suggested by Persson in 1998 and similarly by Popov in his ...

Abstract: A recent paper by Yang et al. [1] shows interesting results on the percolation threshold, the ratio of real contact area to nominal contact area A/A0 when the first leak channel appears across a seal interface. Percolation ...

Abstract: How friction affects adhesion is addressed. The problem is considered in the context of a very stiff sphere adhering to a compliant, isotropic, linear elastic substrate and experiencing adhesion and frictional slip relative ...
